Description

Prefabricated coincide floor bottom plate tip reinforcing bar connection structure Technical Field The utility model relates to the field of building floor construction, in particular to a prefabricated composite floor bottom plate end reinforcing steel bar connection structure. Background The horizontal steel bars exposed from the periphery of the prefabricated composite floor slab extend into the beam template to be poured together with the beam steel bars to form an integral structure, but because the beam steel bars in the beam template are crisscrossed vertically and horizontally, the horizontal steel bars are easy to interfere with the horizontal steel bars of the prefabricated composite floor slab, so that the installation is difficult, the beam steel bars are integrally lifted in a common construction site, then the prefabricated composite floor slab and the horizontal steel bars are placed in place, and the beam steel bars are lowered and returned to the original position. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides a prefabricated composite floor slab bottom plate end reinforcing steel bar connection structure with reasonable structural design. The technical scheme of the utility model is as follows: The utility model provides a prefabricated coincide floor bottom plate tip reinforcing bar connection structure, includes prefabricated coincide floor, prefabricated coincide floor bottom reinforcing bar, sets up beam form board in prefabricated coincide floor outside all around, beam reinforcement in beam form board, prefabricated coincide floor border position all around establishes to domatic, prefabricated coincide floor bottom reinforcing bar exposes in domatic department to buckle and set up and form the reinforcing bar of buckling, set up the connecting piece on the reinforcing bar of buckling of prefabricated coincide floor domatic position, connecting piece one end and the reinforcing bar fixed connection of buckling, the other end stretches into in the beam form board. Furthermore, the top of the bent steel bar exceeds the upper surface of the prefabricated composite floor slab and stretches into the cast-in-situ layer, and preferably stretches into half the thickness of the cast-in-situ layer. Further, the connecting piece is including connecting straight reinforcing bar and articulating the reinforcing bar, connect straight reinforcing bar and buckle the reinforcing bar and set up perpendicularly and fix, articulate reinforcing bar one end and stretch into in the beam template, the other end articulates the setting and just is close to the reinforcing bar position of buckling on connecting straight reinforcing bar, and preferred articulating reinforcing bar is fixed with buckling reinforcing bar ligature. Further, the connecting piece includes vertical bending steel bar and connecting sleeve, vertical bending steel bar includes vertical section and oblique straight section, connecting sleeve sets up on vertical section of vertical bending steel bar, vertical bending steel bar oblique straight section stretches into in the beam template, and vertical section is established on the vertical section of bending steel bar through the connecting sleeve cover.
